If cool, wet weather continues, planting will be delayed for many growers across the Corn Belt. That will prompt questions about switching to earlier season hybrids. According to long-term research studies from DuPont Pioneer and several universities, adapted, full-season corn hybrids usually offer the best yield and profit advantage when planting delays aren’t extreme.
DuPont Pioneer Agronomy Research Manager Mark Jeschke says growers who switch to a shorter season hybrid too soon will give up higher yield potential and profits. Jeschke says hybrid changes should be based on expected grower returns including yield, drying costs and test weight discounts. He says early hybrids should be used under extreme late-plant or replant situations.
